Solid drill bit NSBH-ATH

for hardened steelcarbidedeep hole

"Non-step" processing is possible for all drilling up to ultra-deep holes (L/D=50). NSB special flute shape realizes high chip discharge speed. Compatible with high-precision shanks and shrink fitting Highly efficient machining of ultra-deep holes TH coat with excellent stability even at high temperatures Non-step machining with good chip evacuation with special flute shape Solid guide with W margin Realizes high-efficiency drilling in both environment-friendly MQL machining and internal lubrication machining 01 TH coating with excellent stability even at high temperatures It is a nanocomposite coating material that achieves unprecedented heat resistance and high hardness by adopting a new composition system film made of nanocrystalline materials. Excellent performance for high-speed cutting and high-efficiency drilling in various work materials from mild steel to hardened steel. 02 Good chip evacuation with special Change in spindle load (torque) ●Tool Tool: 20WHNSB0600-TH ● Cutting conditions: vc=100m/min f=0.15mm/rev Hole depth=120mm ● Work material: S50C ●Water-soluble cutting fluid: Internal oil supply
